For this purpose, check which isotope is integrated in the source

container.Youcanndthisinformationonthetypelabelofthesource

container.

Enter here, the respective application.

This menu item enables adaptation of the sensor to the requested ap-

plication. You can choose between the following applications: "Level",

"Density", "Limit level", "X-ray alarm" or "Real value correction".

With this menu item the natural background radiation can be faded

out.

For this purpose, the MINITRAC 31 measures the natural background

radiationandsetsthepulseratetozero.

In the future, the pulse rate from this background radiation will be

automatically deducted from the total pulse rate. This means: only

the component of the pulse rate originating from the source will be

displayed.

The source container must be closed for this setting.

In this menu item you can select the units of the process value and

the temperature.

In this menu item you can enter the measuring range (min. and max.

process value) of the sensor.

Thesesettingsinuencethecurrentoutputofthesensor.

Enter in the menu window "Max. process value" the max. level (full),

for example in "m". This corresponds to an output current of 20 mA.

Enter in the menu window "Min. process value" the min. level (empty),

for example in "m". This corresponds to an output current of 4 mA.

In this menu item you can carry out the adjustment of the sensor.

Due to the measuring principle, there is no linear relationship between

pulse rate and level. Hence, this adjustment (i.e. linearisation) must in

any case be carried out.

Note:

Ifyoucannotllthevesselwiththeoriginalmedium,itisalsopossible

to carry out the adjustment with water.
